Explainer: So far, low risk of human spread of H10N3 bird flu | Reuters
The World Health Organization (WHO) said while the source of the patient's exposure to the H10N3 virus was not known and no other cases were found among the local population, there was no indication of human-to-human transmission yet.
Yet avian influenza viruses that have little impact on birds can be much more serious in people, such as the H7N9 strain that killed almost 300 people in China during the winter of 2016-2017. The WHO has said there had been only rare instances of person-to-person spread of the H7N9 virus.
